Electronic
resources for which SIL pays a fee to vendors have various licensing
constraints; some are explicitly restricted to our Authorized Users.
Authorized Users are those individuals officially affiliated with
the Smithsonian Institution, for example, those registered library
patrons serving in the capacity of full or part time employees,
fellows, interns, individuals under contract, and other registered
patrons who are assigned to an authorized Smithsonian site. Non
SI affiliated library users may access SIL purchased electronic
resources only when they are using terminals physically located
in the library.
